Display device and artificial intelligence server

Abstract

A display device according to an embodiment of the present disclosure includes an output unit, a communication unit configured to perform communication with an artificial intelligence server, and a control unit configured to receive a voice command, convert the received voice command into text data, determine whether the converted text data is composed of a plurality of languages, when the text data is composed of the plurality of languages, determine a language for a voice recognition service among the plurality of languages based on the text data, and output an intent analysis result of the voice command in the determined language.

The invention claimed is: 
     
       1. A display apparatus comprising:
 an output unit; 
 a communication circuitry configured to perform communication with an artificial intelligence server; and 
 a control device configured to: 
 receive a voice command; 
 convert the received voice command into text data; 
 determine whether the converted text data is composed of a plurality of languages; 
 when the text data is composed of the plurality of languages, determine a language for a voice recognition service among the plurality of languages based on the text data; and 
 output an intent analysis result of the voice command in the determined language, 
 wherein the control device includes a plurality of language analyzers, and 
 wherein the control device is configured to determine a specific language as a language for the voice recognition service when a number of words of the specific language among words constituting the text data is largest, based on recognition results of the plurality of language analyzers. 
 
     
     
       2. The display apparatus of  claim 1 , wherein each of the plurality of language analyzers is configured to recognize a named entity and a part-of-speech of the named entity from the text data. 
     
     
       3. The display apparatus of  claim 2 , wherein, when a first language is set as the language for the voice recognition service and the determined language is a second language, the control device is configured to output the intent analysis result in the second language. 
     
     
       4. The display apparatus of  claim 1 , wherein the output unit includes a display device configured to display the intent analysis result or an audio output device configured to output the intent analysis result as audio. 
     
     
       5. An artificial intelligence server comprising:
 a communication circuitry configured to perform communication with a display device; and 
 a processor circuitry configured to: 
 receive voice data from the display device; 
 convert the received voice data into text data; 
 determine whether the converted text data is composed of a plurality of languages; 
 when the text data is composed of the plurality of languages, determine a language for a voice recognition service among the plurality of languages based on the text data; 
 generate an intent analysis result of a voice command in the determined language; and 
 transmit the generated intent analysis result to the display device through the communication unit, 
 wherein the processor circuitry includes a plurality of language analyzers, and 
 wherein the processor circuitry is configured to determine a specific language as a language for the voice recognition service when a number of words of the specific language among words constituting the text data is largest, based on recognition results of the plurality of language analyzers. 
 
     
     
       6. The artificial intelligence server of  claim 5 , wherein each of the plurality of language analyzers is configured to recognize a named entity and a part-of-speech of the named entity from the text data. 
     
     
       7. The artificial intelligence server of  claim 6 , wherein, when a first language is set as the language for the voice recognition service in the display device and the determined language is a second language, the processor circuitry is configured to generate the intent analysis result in the second language. 
     
     
       8. The artificial intelligence server of  claim 1 , wherein the processor circuitry is configured to use a natural language processing engine to acquire the intent analysis result of the text data.
